Hume AI

“Fine” can be a yes or a goodbye. The transcript can’t tell the difference, and most AI reads only the transcript. Hume measures how it was said: tone, energy, delivery, across voice, face and language, in real time.

Voice AI gets judged by users in seconds, on things a transcript never shows. Hume helps teams measure and improve voice AI the way people experience it, across voice, face and language, in real time.

A smile score isn’t the story. Context is. Hume measures expression across face, voice and language in real time, so your product responds to how people actually come across, not just what they type or say.

Five cuts of your next ad. Test them on measured human reactions instead of gut feel, before you spend on media. Expression Measurement reads facial and vocal expression frame by frame, so you can see which moments land and which ones lose people.

“Fine” never means the same thing twice. Expression Measurement hears the difference, natively in 50+ languages. The same word can carry relief, frustration or doubt depending on who says it and how. Our API measures the expression behind the words across voice, face and language, with no translation layer and no English bias.
